112: Number Of Category A Terminals - IBM 3270 Manual

If the sum of the two categories exceeds 32:
e
For Category B terminals, specify the actual number of Category B
terminals (sequence number 111).
e
For Category A terminals, specify the difference between 32 and the
number of Category B terminals (sequence number 111).
Example: 13 Category B terminals
and
17 Category A terminals would be
specified as 13 and 19, respectively. Figure 3-6 shows the relationship
and the ways to specify the various Category A and B terminal quantities.
Note that, when Category A terminal adapters are added or removed, the
host-recognized address of port BO changes. -
Model 51C: Enter a 08 in step 8 on the Initial Customizing Procedure
Form. Although not asked for the Model 51C, the sequence number is
shown on the verification frame with 08 filled in.

*The host-recognized port addresses are sequential, with the first Category A port (port AO) always being address 0 (with the exception
of SNA, which is always 02). The first Category B port (port BO) is always the next sequential address after the last Category A port.
